RHEASREG® KHSSFV-Modbus

Electronic duct top-hat rail air flow sensor RHEASREG® KHSSFV - Modbus with Modbus connection, housing for installation in distribution boards or control cabinets with 35 mm mounting rail, external flow probe incl. mounting flange, for determining the flow velocity (0.1...20 m/s). The following parameters can be queried via Modbus: Flow velocity and volume flow (calculated).



The flow sensor is suitable for monitoring or controlling air flows in ducts, on fans, control dampers, for flow-dependent monitoring of humidifiers and electric heating registers in accordance with DIN 57100 Part 420 or for use in conjunction with DDC systems. Innovative Modbus sensor with electrically isolated RS485 Modbus interface, switchable bus terminating resistor, DIP switch for setting the bus parameters and bus address in de-energized state, LEDs for telegram status display. The sensor is calibrated at the factory.
